Ethylene Detection Tubes 50/a (50 - 2500 ppm)
For short-term measurements more than 160 Draeger-Tubes are available to measure the spot concentrations of specific gases. Measurement usually takes between 4 seconds and 15 minutes. The tubes are used either manually with the Draeger-Tube Accuro Pump or automatically with the Draeger X-act 5000.
A wide range of different gases and vapors can be detected and measured, such as:
- Determining and measuring concentration peaks
- Measuring personal exposure in the inhalation area
- Detecting leaks in pipelines, gas installations etc.
- Air analysis in sewers, shafts and confined spaces
Ethylene Detection Tubes 50/a (50 - 2500 ppm)
| Standard Measuring Range: |
50 to 2,500 ppm |
| Number of Strokes (n): |
3 |
| Time for Measurement: |
approx. 6 min |
| Standard Deviation: |
20 to 30 % |
| Color Change: |
yellow ?> blue |
| Temperature: |
15 to 40 C |
| Absolute Humidity: |
< 30 mg H2O / L |
| Reaction Principle: |
CH2=CH2 + Pd-Molybdate complex ??> blue reaction product |
| Cross Sensitivity: |
Organic compounds with C=C double bonds are indicated, but with different sensitivities. It is impossible to differentiate between them. In the presence of CO, the indicating layer is colored blue depending upon the CO concentration and its exposure time. H2S is indicated by a black color, but with considerably lower sensitivity. |
